摘要: In this work, we investigate the advantages and challenges of deploying a single mobile sink in IEEE 802.15.4/ZigBee wireless sensor networks (WSNs). The first part paper provides an overview most recent research on mobility WSNs, placing special emphasis different types (random, predictable controlled) discussing application scenarios suitable for their respective deployment. second paper, our OPNET model simulation large-scale ZigBee-based is presented. enables effective evaluation random under varying conditions forms routing underlying ZigBee WSN. results obtained using show that terms energy efficiency ZigBeepsilas tree-based outperforms mesh routing, both case mobility. At same time, models, generates longer delays delivery data reporting packets. Furthermore, when compared against each other assuming identical network conditions, shown to achieve higher shorter packet than
